ALBUQUERQUE, N.M. (AP) — Public Service Company of New Mexico says bids to install Environmental Protection Agency-ordered pollution controls at the San Juan Generating Station have confirmed its belief that the EPA underestimated the price.

The Albuquerque Journal reports (http://bit.ly/KnMFG3) that PNM says the lowest bid is more than double the federal agency’s estimate of $345 million to equip the coal-fired plant with selective catalytic reduction, or SCR, technology to cut pollutants that cause regional haze.
